An XBRL object deletion refers to deleting a defined XBRL object such as a context, unit, or footnote. For example, users can delete a defined XBRL unit object from the list of units. In this case, not only is the XBRL object removed; any XBRL mappings within the Office document which are associated with the deleted object are also removed. Note that taxonomy concepts cannot be deleted through Disclosure Management Mapping Tool because they are defined in taxonomies (that is by the Disclosure Management Taxonomy Designer rather than an Office user). Before an XBRL object is deleted, you are prompted with the message: “Are you sure you want to delete this [name of object]?” After you delete an XBRL object, you cannot undo the action, and you must redefine the object and recreate the maps.
